Data Acquisition

Basic Data Acquisition with CODA (updated 11/3)

For this data taking we running the Left and the Right DAq completly independent of each other. The Left DAQ setting takes data for the LHRS and the DVCS calorimeter. For the Left DAQ, the data needs to be taken with (regular) LEFT DAQ prescale 9 only. To switch between different type of triggers in the LEFT HRS or on the DVCS calorimeter, one needs to modify prescale on the DVCS trigger module.

How to run DAQ on LEFT HRS (which is also the DVCS one):

From a terminal login as "adaq" on adaq1 machine (do "ssh adaq@adaq1" without the quotes)

Password is available on the white board

After login to adaq1, type "startcoda" to bring up the runcontrol GUI

The default configuration is "DVCS", if it is not loaded you can choose it from the menu "configurations->Cool", select "DVCS"

Data appear in /adaq1/data1/dvcs14_NNNN.dat.X where NNNN is the run number and X is the split number.
You can find the last run with the command "lastrun"

Changing from the "DVCS" run type to the "LHRSnew" run type

To change from "DVCS" run type to the "LHRSnew" run type, in addition to selecting the proper run type in the RunControl GUI, and adjusting the standard prescales using "prescaleL" on adaq1, you must do the following to disable all trigger inputs for the DVCS trigger crate:

Log into dvcs@intelhadvcs4

Execute the script "~/libraries/dvcs_trigger_2014/DisableAllTriggers"

Optionally, you can execute "~/libraries/dvcs_trigger_2014/PrintStatus" to verify all DVCS prescales are set to zero.

This turns off all DVCS trigger inputs, independently of the DVCS trigger configuration file.
Once the DVCS trigger crate is disabled, the PS9 trigger to the TriggerSupervisor will not have any signals.

This only needs to be done once.

The reverse transition, going from "LHRSnew" to "DVCS" does not require running an addition script, but will require setting all prescales except PS9 to zero in "prescaleL" and adjusting the DVCS prescales. The DVCS trigger crate will reload from the configuration file.

Triggers, Scalers, and Dead Time

For this data taking we running the Left and the Right DAq completly independent of each other. The Left DAQ setting takes data for the LHRS and the DVCS calorimeter. For the Left DAQ, the data needs to be taken with (regular) LEFT DAQ prescale 9 only. To switch between different type of triggers in the LEFT HRS or on the DVCS calorimeter, one needs to modify prescale on the DVCS trigger module.

Standard configuration

Setting prescale factor for the DVCS trigger module (updated 11/20)

The DVCS trigger module forms a LHRS trigger (first trigger level) and initiate the search of a valid photon event in the DVCS calorimeter. If a valid event in the DVCS calorimeter is found (second trigger level) the event is recorded. So when setting prescale factor for the DVCS trigger module, one needs to specify what makes the first trigger level and what makes the second one. For more info goto: [this page]

To set the prescales for the DVCS trigger module, connect as dvcs@intelhadvcs1 (this uses the same password as the adaq account, if you are asked for one), edit file config_files/dvcs_trigger.conf, start the run.

There are four DVCS trigger types that are equivalent to the standard LHRS coincidence triggers:

Prescale_0 Clock = 0; Equivalent to standard LHRS prescale #8

Prescale_4 S0 and S2M = 0; Equivalent to standard LHRS prescale #1

Prescale_5 S0 and CER = 0; Equivalent to standard LHRS prescale #2

Prescale_8 S2M and CER = 0; Equivalent to standard LHRS prescale #3

The DVCS prescale settings are in powers of two:

15

Trigger is prescaled by 16384

Setting prescale factor for the HRS only (updated 11/03)

For this DVCS/GMP run, we use prescale 9 only for the regular LHRS DAQ.

For Left HRS:
login as adaq on adaq1 machine
type "prescaleL &" to open the GUI
set desired prescale factors (for DVCS enable prescale 9 only) and click "Save" and Exit

For Right HRS:
login as "adaq" on "adaq2" machine
type "prescaleR &" to open the GUI
set desired prescale factors and click "Save" and Exit

Raw rates of trigger and detector channels can be accessed using a GUI. Below are the instructions for opening "xscaler" GUI

These screens are generally already open on the agen5 machine (above the DAQ machine)

If it is xscaler is not open then follow these instructions:

login as a-onl on adaq1 or adaq2 machines (eg: "ssh a-onl@adaq1" )

passwords are written on the white board

type "goxscaler" and follow the instructions printed on the screen

type "./xscaler Left" or "./xscaler Right" to access xscaler display

How to download and check the LHRS MLU trigger (updated 11/05)

By default for DVCS, we will not use this system. The HRS trigger (S2m&GC) is formed by the dedicated DVCS trigger module. If for some reason you still need to work with the MLU, consult the MLU information off the main Hall A wiki page.

How to check the dead time

last update 12/2/14
There are two ways to check for deadtime:

online using the XScaler tool.

See above for instructions on how-to open the Xscaler.

Select the "misc" tab.

the ratio (DVCS_stop/DVCS_masterOR) is a measurement of the live time for our main trigger.

Starting CODA From Scratch

You do not need to do this routinely - only if you are starting from a fresh login or after a computer crash.
Log in a a-onl account on adaql2 ( check with Run Coordinator in case you don't know the password )

Power cycling Fastbus crates

Reboot crates

On one workspace you will see six xterms with names of the crates in
the title, e.g. "ROC4--hallasfi4--hatsv40-port6".
From each of the six xterms, you should telnet into the appropriate RS232 interface, e.g. for the above, "telnet hatsv40 2006" (if the prompt in the xterm is "->", it is already connected). The "hallasfi4" is the internet name of the crate's cpu.

If the xterms are missing, type "setupxterms".

From these xterms, you reboot by typing "ctrl-X". Yes, you hold down
the Ctrl key, then hit X. You can also type reboot but "ctrl-X" is
better. You can also reboot from the crate resets GUI on HA Tools.

To power cycle the DVCS crates, type crateOff in a terminal in logged as a-onl and after crateON to turn both ROC17 and ROC18 back on.

For full details about the Hall A DAQ (including reboot procedures) see This or This

If you have trouble downloading to ROC31

If ROC31 (or one of the other Intel CPU crates) gives errors in the "Configure" or "Download" steps, first try the following:

In RunControl, select the "Release Components" option under the "Platform" menu from the top menu bar.

In a terminal on adaq1, run the command "killdvcsrocs"

In a terminal on adaq1, run the command "dvcsrocs". Terminal windows for ROCs 27-31 should appear.

Select the "Configurations/Cool" menu, and select the proper run type (as of 22Oct2016, it should be LHRSBuf).

Now try to configure and download.

If it fails to configure or download again, try this once again, but do "kcoda" and "startcoda" instead of the "killdvcsrocs" and "dvcsrocs".

If still fails, try rebooting ROC31 as described below and call P.King (number on whiteboard).Note that if you reboot ROC31, the EDTM system will need to be restarted; see How to start the EDTM system or call an expert.

Reboot DVCS crates (New)

If a ROC fails to configure or download, see if the ROC window is still visible.

--If it is visible, do the folowing:

Type 'kcoda' at a terminal (as user adaq on adaq1 machine).

Type 'killdvcsrocs' at the same terminal.

Type 'startcoda' at the same terminal to initiate a new session.

--If the ROC window cannot be seen, do the following:

Type 'kcoda' at a terminal (as user adaq on adaq1 machine).

Type 'killdvcsrocs' at the same terminal.

Telnet to the port connected to the ROC you need to service (e.g. telnet hatsv21 2002). ROC27 is on port 4 (2004 ) , ROC28 on port 3 ( 2003 ), ROC29 on port 2 (2002) , ROC31 is on hatsv4 port 2

Type 'q'

Type 'CAEN'. (Nothing will display on screen at you type.)

A menu with options to control the Crate will appear. Type 'C' to view the status of the crate.

If the crate is off, type the letter 'o' to turn it on.

Type the letter 'q' twice to leave the crate control.

Type 'ctrl+]' to exit the ROC.

Type 'q' at the "telnet>" prompt.

At the terminal, type 'dvcsrocs'. See if windows for all ROC windows appear. If they do, type 'killdvcsrocs'.

Type 'startcoda' to initiate a new session.

--a remote power switch is installed on DVCS rack mostly for the trigger and VME trigger crate

How to Take a Pedestal Run

HRS pedestals

If you've been running the normal spectrometer DAQ configuration, you'll need to press "Abort", then "RunTypes" and select the PEDRUN configuration. Download, StartRun. Run for about 5000 events, then EndRun. You may check the pedestal files in ~/ped (pedN.dat corresponding to ROC #N). See README there for more details. After pedestal run, change back to the running configuration.

NOTE: DONT try to use PEDRUN for anything other than pedestal determination -- its confusing since the prescale factors are in a different file, etc. If you want a run with pedestal suppression turned off, see the README.

EDTM: older instructions that Longwu OU wrote

Intel Version

The crate containing the random pulser has both a Vxworks CPU (happex8) and an intel CPU (intelha3). As this crate is being used to read some F1 TDCs, using the intel ROC, the r_pulser library has been ported to Linux to run on intel ROCs, in case the Vxworks CPU needs to be reomved from the crate. This ported version is in /root/rpulser on intelha3. The available commands can be seen by running

/root/rpulser/rpulserl usage

The pulser can be started with

/root/rpulser/rpulserl start 0 0xa100 0xc339

This command has been placed in the boot script for intelha3. The equivalent command has been commented out of the boot script for happex8.

Using flexio module for EDTM measurement

The output of port B of the pulser generator goes to a NIM fan-out module and is then fed into two flexio module. Each module has two output cards and each card has 16 channels. The first module (which has 32 channels in total) provides EDTM pulse to the 32 S2m PMTs, one card for left side and one card for right. Only one card of the second module is used now, and its 14 outputs pulse 10 GC PMTs, GC analog sum and S0 PMTs respectively. Each channel of the output card can be enabled or disabled by setting the corresponding bit of the register.

For GMP and DVCS experiment, S0 and GC PMTs are always pulsed with EDTM signal, while only 2 S2m PMTs attached to two sides of a scintillator paddle are pulsed at one time. Their signals are mixed with EDTM pulse for a little while and then the 2 PMTs with next paddle are pulsed. In this way all 16 paddles get looped over again and again. The command to initiate flexio module to work in this manner is

When two arguments are provided for the program flexioctl, the first one is the duration (in minutes) of the program. When the program expires, it stops setting the register of flexio module so the loop over S2m paddles will stop. The second argument determines how long each paddle is pulsed in seconds. In the case only one argument is given, this argument does exactly what argu2 does in the other case, and the program will practically run forever.

Data analysis

How to replay the data

If you are the third person in shift: first replay 50k events, check the online display, then replay the whole run.

Login to aonl1, aonl2, aonl3, or aonl4 as user a-onl (password on the white board) and run

$ godvcs
$ analyzer
[].L replay_DVCS.C
[]replay_DVCS(runnumber)

The rootfile is copied under /chafs/work1/dvcs/Rootfiles/left_dvcs_[run number].root. To look at the data you might want to use the online GUI (see the instructions below).

OnlineGUI

(Last updated: November 06, 2014)

Once the run has been replayed (see instructions above), login to aonl1, aonl2, aonl3, or aonl4 as user a-onl (password on the white board) and do

The output files are stored under /chafs/work1/dvcs/Rootfiles/left_dvcs_[run number].root

For more detailed information on the online GUI, please see the README file at /adaqfs/home/a-onl/dvcs12/onlana/README.

Batch offline analysis

As soon as CODA files go to /mss, a batch job is submitted to the JLab farm to decode each file. Outputs are store under /mss/home/munoz/DVCS2/1stprod. A copy of the last 100 files is kept in the work disks under /work/halla/dvcs/disk1/1stprod.

Spectrometer detectors

How to change the momentum setting of HRS

From the HAC window, there is a P0 SET field for each spectrometer in which you can enter the desired momentum setting. To change to a lower momentum from a higher previous setting, you just need to enter the new momentum value. To raise the momentum setting, you need to cycle the Q2 and Q3 magnets first and then enter the desired momentum setting.
To cyle the Q2 and Q3, turn off their regulation (Hall A General Tools, click the button right of P0set), send Q2 and Q3 to 1600 A, wait two minutes at 1600A, set the p0 to the deisred value, turn onn Q2 and Q3 regulations.
If you run into trouble with the dipole NMR lock, [this] might help you.

How to change the spectrometer angle

First, do a visual survey of the Hall to make sure nothing is in the spectrometer's path. Also, make sure you are not exceeding the minimum (typically 14 degrees) or maximum (experiment dependent) spectrometer angle.

For DVCS/GMP Spring 2016, the maximum angle for the LHRS is 45 deg, the RHRS is 55 deg.

The DVCS calo is between the beam line and the RHRS, decreasing the RHRS angle can potentially result in crushing the DVCS Calo (not good). Check with the RC !!

Typically any motion less than 14 degrees requires techs to be present in the hall

Second, on hacsbc2, click the red "tool box" icon on the linux taskbar, as above. Choose bogies_SetSpec so that you can determine the angle and vernier setting for the spectrometer.

See the window displayed to the right. Enter the spectrometer (L or R), and the angle, and you will get two options for the floor mark and the vernier. Generally choose the vernier closer to zero. Center the cameras on the desire vernier using the Move+/Move- buttons on the Hall A General Tools screen. The TV monitors for these cameras are on the middle shelf, in rack CH01A05.

Third, choose bogies_Left (or bogies_Right) in the tool box to bring up the bogies control screen. [image:bogies_RIGHT.window.gif] Click PSM enable and wait a few seconds for PSM OK to read YES. Click DM enable and wait a few seconds for DM OK to read YES.

Make sure the velocity is set to 0 and the direction is CW or CCW as desired. Click on Brake Release and wait for Brakes OK to read YES.

Click on ClampRelease, set the velocity to 400 (do not exceed this value). Once you see the spectrometer start to move in the floor angle camera - you cannot see the spectrometer move in the Hall overview camera, as it only moves a few degrees per minute at maximum speed. For the left arm, to move to a larger angle, the direction should be CCW, while for the right arm CW moves the spectrometer to larger angle. The direction of the spectrometer is reversed by using a negative rpm. Watch the spectrometer motion on the cameras. When you are getting close to the desired angle, slow down to about 300 rpm. To stop, click on the Clamp Release button and the Brake button. Disable DM and PSM, and disconnect to close the GUI. Read off the floor angle mark and vernier, and input the values into the appropriate fields in the Alignment section of the Hall A General Tools GUI.

If the bogie become unresponsive, you might read the section below on how to reset the bogie.

How to reset the Bogie IOC

Sometimes the HRS bogie controllers get in a funny state and will not respond to the GUI.
For example, you click on the buttons (PSM enable, DM enable, etc), but the state field doesn't change, even after a patient wait of 5--10 seconds.

The first thing you should try is to close the Bogie GUI window using the disconnect button, wait for 5 minutes and try again. Sometimes the system will correct itself.
If it doesn't you may want to try rebooting the Bogie IOC.

How to reset the quadrupoles

The reset for Q2 is simple, on the front of the power supply there are red lights on when the power supply is tripped. At the bottom of the board that has the red light there is a blue reset button. There may be more than one light on so there may be more than one blue button that needs to be pushed. Push blue buttons until all of the red lights are out. Once all of the lights are out, lower the large lever on the lower right side of the power supply and lift it back into position. this will reset the Q2 and Q3 power supplies locally. For Q1, it's simpler : there is a large sign in the back of the Q1 equipment rack on the power supply balcony that says the blue reset button is here. you press the button and the magnet resets.

How to reboot HRS magnet IOC

Go to the hall A main menu screen.

Click "IOCS". Note that the left HRS magnet IOC's (iocha14) are accessible at http://hareboot10 and the right HRS magnet IOC's(iocha16) are accessible at http://hareboot25 (Username and password for IOC reboot are available in the counting house). Close the "Hall A IOC Systems" window.
To reboot:

the left HRS magnet IOC's, go to http://hareboot10 and from the pull-up menu next to iocha14, select "immediate reboot".

the right HRS magnet IOC's, go to http://hareboot25, click on control, select iocha16, from the pull-up menu select "immediate reboot".

After the IOC reboot, please make sure that the spectrometer-angle information is reentered into the Hall A General Tools GUI.

How to restart the HRS hall probe gaussmeters

The Lakeshore gaussmeters for the magnet hall probes are no longer being
controlled by the Slow Controls VME crates (iocha14 and iocha16). You will
notice that the GUI for each gaussmeter is slightly different than the
previous GUI. The functions are still the same. However, if a meter "hangs", a
person must notify accelerator Software On Call to reset the interface; ask
MCC to make the call. At present this is not something we can do from the
Counting House.

DO NOT attempt to reboot iocha14 or iocha16 to correct
any problem with a gaussmeter readout. The control is now done through a
portserver with an Accelerator PC acting as a "soft"-IOC. We do not have
direct access to this PC.

How to start xscaler (HRS) / view the scalers

start xscaler :

Go to the hapc5 terminal in the middle of rack CH01A09. If it is not logged in, log in as user "adaq"

Type ssh adaq@adaql4 and enter the password when prompted.

Type goxscaler

Type ./xscaler

to view the scalers :

The simplest : login to adaq l1 as adaq

Type xscaler

Follow what it says

NB : you must be in the correct directory since there are 2 versions of xscaler : the new is ROOT GUI (the previous one is Calvin Howell's GUI)

Beam Line

Is the raster on?

One way is to check the raster current on the scope ( but right now the scope has disappeared).
Another way is to connect to JTAB, go to the Hall A tab and type "raster" in the search box.

How to Check the Raster (spot) (updated 11/08)

In order to properly analyze data from the raster and bpm runs, whoever is taking the data will need to use the spot_Left code located in my directory. The standard spot++ analyzer has not been updated to include the second (downstream) rasters.

The instructions are:

login as a-onl on adaq1 (eg: "'ssh a-onl@adaq1").

passwords are written on the counting house white board

cd to the rastersize/luke/ directory

From the terminal, type"./spot_Left runnumber max_number_of events" (without the quotes, and where runnumber and max_number_of events should be integers)

How to do harp scan

Go to the JTabs menu and select tab "Hall A", then "ARC Integral" and after that click tab "ARC Scanners". A window named "New ARC" will pop up. Six charts are in this window and below each chart there is a blue box with the current value of gain. To do harp scan we need to have CW beam above 5 muA and the gain should be at least 16, and beam position should be stable.

Since the beginning of 2016, MCC is in charge of the Harps. Just request the harps to be done by them and make sure they post their result in the log. On JTab, under the operation tabs, you can look at the most recent raw harp scan by selecting the Harps button and then harp history.

How to check for Parity settings (beam half wave plate and Wien angle)

Our standard configuration is 30 Hz, prompt helicity reporting.

These settings are outputted in the run start and run end entries in the halo. But if you do not have a recent entry for those can also do the following:

go to the JTABS menu, choose the INJECTOR tabs, then choose Parity and then Parity Controls. Look for Insertable WavePlate.

go to the JTABS menu, choose the INJECTOR tabs, then choose Spin then Spin Control. Look for the HWienAngle.

How to record info for the arc energy measurement

Compton Operation

Take Compton data

The Compton DAQ is located in the back room in the Counting House (look for the Compton computer under the small LCD screen).

CODA runs on compton@compton. If CODA is not already running:

Kill CODA first, then start it up again:

$ kcoda
$ startcoda

A few new Terminal windows and a GUI pop up. Let "top" refer to the bar with named menu options near the top of the GUI (ex: Platform, Sessions, etc). Let "bottom" refer to the bar below "top" that contains a line of buttons (hover over them to reveal their labels; starting with "Configuration" on the left).

In top, select: Platform > Connect

In bottom, click on "Configuration" button.

If configuration listed in the "Run Parameters" box is not FADC_prod: in top, select Configurations > Cool and change it to FADC_Prod.

In bottom, click on "Download" button

In bottom, click on "Prestart" button

When ready to start run, click "Start" button. Typical run duration: 2 hours. Type in any Start Of Run comments in the box.

When ready to stop run, click "End" button. Type in any End Of Run comments in the box.

Make sure the Compton photon detector is on

The Compton photon detector HV is on the BEAMLINE HV gui which should be up on hapc3. The photon detector is slot 12, channel L4.11.HV=-1690 V.

Check the Compton rates/slow signals

Look at the strip chart running on adaq2 on the "Compton" desktop. If the strip chart is not up, you can start it as follows:

ssh compton@compton-old

StripTool compton_monitor.stp

Make sure the laser is cycling on and off (the green trace labeled COMPTON_PW1PCAV_ca).

Check for collisions - the photon detector rate should increase and decrease as the laser cycles on and off (blue trace - ComptonCentralRate).

Check rates. The laser-off rate in the photon detector should be below 500 Hz/uA. Closer to 100 Hz is better.

Make sure the Compton position lock is on. If the vertical beam position is changing more than 0.1 mm (IPM1P02B.YPOS), the position lock is likely not on - call MCC and ask them to make sure it is.

The laser-on rate should be on the order of 1 kHz/uA. If it is smaller than that, we might need to scan the electron beam. This is done by a Compton expert.

What low Compton rates means

How to check that the Compton electron detector is out of beam

Slow control

How to bring up HAC control window (Hall A Tools), Monticello and JTabs

We like to run this display on is hacsbc2. The monitor is located in the Hall A Counting House in rack CH01A02, just below the NMR dipole oscilloscopes. Click here to see the screen.

If the display is not here: log onto the a-onl or the adaq accounts:

Hall A Tools: 'hlamain'

JTabs: 'jtabs'

Monticello" 'monticello'

JTabs is the newest version of the accelerator tools (it replaces monticello) and has some overlap witht he old EDM monticello and hlamain GUIs. It is most likely to be up to date and working, but maybe missing some items from the EDM tools. [Original halog with nice pictures

High Voltage controls (updated: 03/15, K.Park)

LHRS/RHRS : High Voltage controls

Login as "adev" on the "adaql1" or "adaql2" computers.
(since I have added voice alarm for LEFT, RIGHT HRS and Compton HV, please note that command is different !)

cd ~adev/slowc

To run the Left HRS alone: ./hvsL LEFT

To run the Right HRS alone: ./hvsR RIGHT

To run the beamline (Compton) crate: ./hvsC BEAMLINE

The following instructions can be used for running the GUI using the vnc server How to open high voltage GUI. This is not how we want to run routinely.

For a moment, we have only an alarm related with VME server status (129.57.242.13). If lost connection, there is an audible alarm.
Reaction:
(1) ping 129.57.242.13 to make sure it is a connection issue.
(2) if there is no ping result, you should reboot the VME by remote power-cycle.

DVCS Temperature Monitor

The motivation is to investigate the pedestal oscillation (possibly temperature dependence, air condition run cycle...)

At lease this allows us to monitor the temperature inside of dark-box
The sensor installation is shown in the attached figure. (top of calorimeter frame)[Picture]
We used the 33ft x 2 USB extension cables for the connection between sensor and dvcsdaq2 computer(down the hall).

script is running under on DVCS@DVCSDAQ2.jlab.org

This plot shows the temperature history between -8hrs and Now.

DVCS HV alarm

If you hear about DVCS HV alarm (either Red flashing rectangular box on screen .OR. Voice),
please look at the DVCS HV GUI which is running on aonl2.jlab.org machine then figure out the what the problem is.

HRS HV alarm

If you hear about Left/Right HV alarm (either Red flashing rectangular box on screen .OR. Voice),

Starting HALOG

For the standalone halog utility: 'ssh adaq@adaqX' ; 'halog'. This will submitt to the new logbook.

Enter text in the large message area, your name in the User area, and a title in the Subject field. Remember that experiments tend to suffer from too little documentation, not too much. Also, halog entries allow people to remotely check on the experiment progress without bothering you with phone calls. When complete, after pressing the "Make Entry" button, the text in the message center at the top of the window should read 'Entry was saved with lognumber <XXXX>', otherwise something is wrong. It may take a minute or two for the entry to show up in the logbook.

Making a screen snapshot: Click 'Add Attachment' in the bottom button row of the halog window. The halog window will disappear, and the window the cursor is in will become the active window, its outline flashing. By moving the cursor you can select any window to be selected, by clicking on the left mouse button. You also can select an arbitrary part of the screen by holding down the left mouse button and dragging the cursor along. All the time a rectangle will flash that indicates the selected area. Releasing the mouse button will then cause this screen area to be included into the entry. It will show up as a thumbnail picture in the halog window, where you can discard it or accept it, and then make a second screen grab.

How to bring up the Alarm Handler

From the "toolbox" icon in the taskbar, press the "Alarm Handler" label. Alarms are indicated by a beep and the alarm handler button flashing. The color red indicates values far out of range, while the color white indicates a communication failure. Clicking on the alarm handler button will bring up an alarm handler list. A detailed list is given in the left panel, and clicking on items here brings up a more detailed list in the right panel. The alarm can be acknowledged and silenced by clicking on the button beside the alarm indicator.
[This Halog entry] has some more info about the alarm settings.

What/where to check target temperature and pressure

The target temperature and pressure is displayed on the target GUIs running on cryotarg as well as on the camera monitors in the rack (CH01A06) left of the target computer. Look at the camera monitor on the top right of rack CH01A06. It displays the temperatures for the three loops on three white temperature controllers, with loop 1 at the top and loop 3 on the bottom. Ask the TO for help if you can't find the temperature or it doesn't make sense. The adjacent camera displays the JT valve controller readings and tachometers.
